Problems solved by technology

However, due to the lack of a suitable chip driver, the essence of the solution for realizing the DSI3 interface in the prior art is to realize the simulation of the DSI3 interface through discrete devices, and it is impossible to truly realize the function of enabling the simulator to have a DSI3 interface.

Abstract

The invention provides a sensor simulator with a DSI3 interface and an interface implementation method. The sensor simulator comprises a micro-control unit which achieves bus communication with a terminal through a bus transceiver; a plurality of DSI3 driving chips with which analog signals output by the micro-control unit communicate through a serial port, and which convert data into data in a DS1 bus form and send out the data; and a power detection circuit. When a vehicle body automatic parking controller drives an ultrasonic sensor to be detected to work, the terminal sends an instruction to the sensor simulator through a bus, and the sensor simulator carries out data interaction with the vehicle body automatic parking controller through multiple paths of DSI3 data channels, sends an analog signal to the vehicle body parking controller and receives state data fed back by the controller. Therefore, a discrete device used for simulating a DSI3 interface in the prior art can be replaced, and a DSI3 interactive interface between the sensor simulator and the vehicle body automatic parking controller is realized by adopting a sensor driving chip.

Description

technical field [0001] The invention relates to the technical field of sensor equipment detection, in particular to a sensor simulator with a DSI3 interface and a method for implementing the interface. Background technique [0002] Different automatic parking solutions use different methods to sense and detect obstacles around the vehicle. A commonly used technical solution adopts the method of ultrasonic wave and visual fusion, and installs ultrasonic sensors at both ends of the front and rear bumpers of the vehicle to form an ultrasonic induction radar circle covering the outer contour of the vehicle. When parking, the ultrasonic sensor continuously sends signals to the surroundings, and at the same time receives the signals returned by the surrounding obstacles, and determines the distance of the obstacles according to the time difference between the sending signal and the receiving signal. [0003] Naturally, this automatic parking technology has high requirements on th...
